INVENTOR Patented Oct. 21, 1930 HOWARD J. MURRA Y, OF BROOKLYN, NEW YORK REMOVABLE SOCKET AND REFLECTOR Application filed October 22, 1926. Serial No. 143,369..

My. invention relates in general to a combined socket and reflector for use wherever such a device can be utilized and the invention specifically relates to a combined detachable socket and reflector for use with signalling and lighting devices as commdnly found on movable vehicles.

. Sockets of the type nowgenerally known are designed so that screws or bolts and nuts are necessary to suitably mount same to the 1 maintained by occasionally renewing the' walls of the .container enclosing the lighting means. When it becomes necessary to renew the lighting means the lens has to be removed. This requires tools which are not always available and in addition the removal disturbs the security of the lens as repeated removals with improper tools damage the container. Furthermore, in case of darkness it is very diflicult to remove the lens even when equipped with proper tools. 6

- Accordingly, this invention features a socket which can readily be removed from the container by the hand 'and without tools.

The lamp then may be replaced in the usual manner, or in case of a defective socket same can be replaced by simply disconnecting the v conductor.

Another object of the invention is to provide a socket of such shape that a portion of same will act as a reflector of the light from the said light source. Signalling devices as commonly found on movable vehicles depend on painted surfaceswhich become soiled or scratched and thereafter lose efliciency. Because of the necessity in some cases of using such signalling devices in daylight it is imperative that the reflecting surface be as efiicient as possible in order to permit the use of small candle-power lamps and thus conserve the. charge of the storagebattery. A manually. removable socket with a reflecting surface would enable such'efiiciency to be socket.

l S A still further object, of the inventiomis to provide a renewable socket with a separate reflecting surface designed to be manually ins' r'ted with the said reflector. As such a reflector is of extremely simple design and low cost, reflecting efliciency canbe easily and cheaply maintained. It is evident that the reflecting surface may be of any suitable form and thus proper reflection of light may beefl'ected for a given signal device, Or the reflector may be varied without changing the container.

Furthermore, it is evident that in case the electrical portion becomes defective manual removal of the socket will instantly determine the cause as the socket will be removed from the body of the container.

Various other objects and advantages of a the invention will in part be obvious from an inspection of the accompanying drawings and in part will be more full set forth in the following particular description of one form of mechanism embodying my invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

In the drawings,

Fig. 1 is an assembly side elevation in partial section of one form of my invention to show the internal construction on the line AA of Fig. 2.

Fig. 2 is an assembly rear view with a portion in section to show the locking arrangement; I I Fig. 3 is a front assembly view showing the location of .the resilient holding means and the use of the face of the socket as a reflector.

Fig. 4 is 1 a side view of the socket showing the cut-awayzportion constituting the securing means.

Fig. 5 is a front view of the socket showing the reflecting surface and the slots for locking and positioning.

. Fig. 6 is a front elevation of a detachable.

reflector arranged to be used with the socket as shown by Fig. 5.

Fig. 7 is a sectional side view of reflector shownby Fig. 6. Fig. 8 shows a partial 'vei'tioar section socket having a curved reflecting surface and a locking and positioning flange.

Fig. 9 shows a par ial vertical cross-seetion of a detachable reflector designed for use with the socket shown by Fig. 8 when casing12. The face.

I lamp p'ece and forming an openin in the shape a tube Whose sides are para lel. Resilient means 26 are rigidly secured to the wall of the 'container 10 by rivets '27. The resilient means are bent so as to cause the portion 35 to project slightly outside th wall-.10.

A socket composed of a casing 12, including a face 17 and an outer portion .18 is securely fastened to the'container 10 by means of the projection 21 formed from the flange 11 belng held against a slotted face due to the pressure of the resilient means 26 against the face 17.

Securely attached to the casing 12 is an insulating'member 13 positioning and holding a spring contact 16 arranged to connect a v lamp 22 to a conductor 14 held con uctor 16 by screw 15.

The lamp 22 is securely fastenedto the casing 12 by means of the pin 36 of the lamp .base pushing against the wall of the cutaway portion 38 of the said casing due to the pressure of the spring in'contact 16. This arrangement is similar to that usually g mployed in attaching lamps to sockets.

' In Fig. 2 is indicated a rear-view of e assembly shown by Fig. 1. The end 16 of the resilient contact member is shown in the end of the insulating member 13. The figure also indicates the method of sliding the flanged portion 18 of the casing 12 into the I flanged portion 11 of the container 10. The section also shows the cut-away portion 20 of flange 18 and the depressed portion of-the i .45 flange Fig. 3 shows the front elevatign-of the assembly indicated by Fig. 1. The lamp 22 is shown in its relatiy osition to esilient means 26 pressing a inst the fa 17 of the 7 is also shown as a reflectir2ig medium of the light from the 2 L 7 Fig. 4 shows the socket alone and indicates the form of the-locking portion of the flange 5 18 of tlie casing 12. The hooked portion 37 prevents the depressed pBrtion 21 of flange 11 (see Fig. 1) from being displaced when tension is appliedto the. face 17 by resilient means-26 (see Fig. 3). a

Fig. 5 is a front view of the socket'shown in Fig. 4 and indicateslthe front portion of the spring contact 25; the coves 24 designed to permit the passage of he pin; .361in'to the slot 37 and finally into the lockin'g'chamber 38 (see Fig. 1). Theslots l arecut away to the said hooked portion-37.

"in order to allow the flange 18 to be passed into the flange 12 while the depression 21is guided into the locking surface 20 (see Fig. 4) by the said slot. -The face 17 has a reflectin surface-36.

In h ig. 6 the feflecting surface 36 is separated from the socket face and becomes the reflecting disc 28 havin slots 29 .designed to permit the passageo the pins'36 of the lamp base of lamp 22 (see Fig. 1).

l/Vhen a curvedqeflector base is required the flange 18 may be formed from a face 31 extending from the opposite end of the casin 12, as shown by.Fig. 8. A mating detac able reflector may be formed as 32 of Fig. 9 to fit the socket of Fig. 8, and-be held against same by the resilient means 26 as shown in Fig. 1.

Themethod of inserting the reflector and socket and of detaching same may be de-rss scribed as follows:

The reflectors of Figs. 6 and 9' are passed over the pins of thebase of the lamp 22 which is then attached to the socket casing 12 in the usual manner. The lamp, socket and reflector are then taken in the 'hand and the socket is pushed into the flange 11 so that the depressed portion 21 will be passed through the slot 19 (see Fig. 4) for a distance to permit the rotation of the socket to enable the depression 21 to pass the locking hook 37. Before such a distance is negotiated the face of. the reflector 28 will press against the resilient member 26 and actuate same caus- 'ing a resistance to the further movement of. 10

the said reflector. The reflector will then be I passed back against the face 17 and a further movement of the-casing 12 willincrease the resistance of the resilient members 26.

After the casing hasbeen rotated a suf-L. 1 5 ficient amount thehand is removedand the a depression 21, will prevent the members 26. from ejecting the socket casin and preent the depression 21 from passing over the It is evidentthat the operation is the same without the reflector, and that the flanges will hold the socket in position airiall It is also evident that the refle ting surface may be placed on a separate member'or be a portion of the socket. I
